Graphing My Class Ring!

Photo_graph_&_plane.JPG
This is an extreme close-up photograph of my class ring. I chose to graph the blue jewel at the top, as it formed a perfect ellipse.




Equation of the graph: [(x^2)/4] + [(y^2)/9] = 1

Domain: [-3,3]
Range: [-2, 2]
Discontinuities: None
Symmetry: Symmetry across the x- and y- axis.
Even, Odd, or neither: Even
[{(-x)^2}/4] + [9y^2)/9] = [(x^2)/4] + [(y^2)/9]

End Behavior: Does Not Exist
